IMPROVEMENT IN ARGAND GAS-BURNERS.

Specification forming part of Letters Patent No. 122,382, dated January 2, 1872; antedated December 19, 1871.

To all lwhom it may concern.-

Bet known that I, HIRAM W. HAYDEN, of Waterbury, in the cou'nty of New Haven and State of Connecticut, have invented and made an Improvement in Argand GasBurners; and thetbllowing is declared to be a correct description thereof.

Argand gas-burners have before beenv made with a hollow cylinder into which the gaseous hydrocarbon is admitted; they, however, are

frequently inconvenient to light, and are influenced by passing atmospheric currents. My present invention is made for regulating the currents of air passing' to the iiame, and allowing the chimney and chimney-holder to be removed with facility for lighting or cleaning.

In the drawing, Fig. l is a vertical section of the said burner, and Fig. 2 is a plan of the Same.

The exterior tubev a and interior tube b are united together at their upper ends by the ring the cone r. The distributerd regulates the quantity of air admitted, and a portion goes by the elbow e and central air-tube b, and the ,other portion passes through holes u in the Germain or student lamps; hence the flame' will be intensified by the impingement of the air upon the same and a very bright light produced and less gas consumed than with the ordinary argand gas-burners. Beside this, the burner, being made of sheet metal, is very strong and much cheaper than those before constructed. I have shown the said chimney in dotted lines at m.

I claim as my invention- The argand gas-burner made of a tube, a, connected at the lower end to the coupling w, and containing the interior air-tube b and elbow c, in combination rWith the air-distributer d and chimney-holder o, substantially as set forth. y
